"I went to this contest, thought it was fun, and I ended up winning. And once you start winning these things it's like a snowball. And you have to go to the next one and if you win there you go to the next one, and I kept winning all the way until the Miss USA pageant," she said.

Frankel, meanwhile, worked as a production assistant on Saved the Bell in her early career.
